It’s been well known for a while that Ken has some nasty meaty setups in Street Fighter V, and these just make his setups even more ambiguous. By connecting his light Tatsu off of a juggle after a V-Trigger confirm, he can actually switch sides. This makes your opponent’s back roll increasingly dangerous for them. You can further make this more deadly by incorporating cross-up air Tatsus after the side switch, making them further guess which side you’ll end up on for the meaty.
